[[iTunes]] gets a couple things from the phone: the [[DeviceID]], the [[CHIPID]], the [[wikipedia:IMEI|IMEI]], the [[Wikipedia:ICCID|ICCID]], the [[Wikipedia:IMSI|IMSI]], the phone number (!), and a few other things. This is called the "activation token" and is unique to every iPhone. This token is then sent to the Apple server (alfred.apple.com) via [[Wikipedia:Transport Layer Security|SSL]]. If the phone number can be matched to the ICCID and IMSI and if the rest of the data is correct, the server appends the [[WildcardTicket]] to the token, signs the token with Apple's private key and transmits it back to [[iTunes]]. [[iTunes]] then calls [[AMDeviceActivate]] with this signed token. The device gets the token and checks whether or not the signature matches the token. If it does and if the baseband is able to log in to a GSM network, the device is activated. A patched [[lockdownd]] circumvents these checks rather then to provide a valid token.
